RCB - 20220110 - Recommend NFA due to good
response, good program, and relatively small amount.'
Dear Mr. Snider,
This letter is in response to the Notice of Violation and Recommendation for Enforcement Letter
dated December 1, 2021 received by the City of Greensboro. The address where the violation
occurred and the amount spilled is shown below:
1. 7625 Thorndike Rd. 3,600 Gallons
The sanitary sewer release on September 18, 2021 at 7625 Thorndike Rd. was due to debris in
the 8" sanitary sewer at this address. A combination jet truck was dispatched to unstop the
blockage and clean the line. Once the sanitary sewer overflow was stopped, we thoroughly
cleaned all lines in the area to ensure we could perform a CCTV inspection of the lines, and we
found no deficiencies to correct.
The spill duration extended longer than expected due to a large -sized rock logged inside the
sewer main that had to be broken apart by the combination sewer cleaning truck to remove. We
inspected the manholes in the area to ensure that we would not have any issues in the future.
Remediation efforts include opening fire hydrants to flush the affected area, and we spread lime
to minimize the spill's impact.
It is our duty to comply with the requirements of Collection System Permit Number WQCS00006
and G.S. 143-215.1(a)(1), and we will continue to address unforeseen circumstances as quickly
as they occur. If any additional information is required, please do contact me. We appreciate
your review and welcome your feedback.
Sincerely yours,
Robert Martin, Construction and Maintenance Supervisor
